DSC8003 Series Programmable Low-Power Precision CMOS Oscillator 1.8~3.3V General Description Features Frequency Range: Programmable from The DSC8003 is a programmable silicon MEMS 1 to 150MHz based CMOS oscillator offering excellent jitter Exceptional Stability over Temperature and stability performance over a wide range of o 20 PPM , 25 PPM, 50 PPM supply voltages and temperatures. The device Operating voltage operates from 1 to 150MHz in increments of o 1.71 to 3.60V 100Hz (up to four decimal point resolution) with Operating Temperature Range supply voltages between 1.8 to 3.3 Volts and o Ext. Industrial -40C to 105C extended temperatures from -40C to 105C. o Industrial -40C to 85C The DSC8003 has the same functionality and o Ext. Commercial -20C to 70C performance as the DSC8001 but with greater Low Operating and Standby Current output drive (C =25pf). L o 7mA Operating (40MHz) o 15uA Standby The DSC8003 incorporates an all silicon Ultra Miniature Footprint resonator that is extremely robust and nearly o 2.5 x 2.0 x 0.85 mm immune to stress related fractures, common to o 3.2 x 2.5 x 0.85 mm crystal based oscillators. Without sacrificing the o 5.0 x 3.2 x 0.85 mm performance and stability required of todays o 7.0 x 5.0 x 0.85 mm systems, a crystal-less design allows for a Excellent shock and Vibration higher level of reliability, making the DSC8003 Resistance ideal for rugged, industrial, and portable Lead Free, RoHS & Reach SVHC applications where stress, shock, and vibration Compliant can damage quartz crystal based systems. Available in industry standard packages, the Benefits DSC8003 can be dropped-in to the same PCB Pin for pin drop in replacement for footprint as standard crystal oscillators. industry standard oscillators Semiconductor level reliability, significantly higher than quartz Frequency Resolution to 4 decimals Block Diagram Short mass production lead-times Longer Battery Life / Reduced Power Compact Plastic package VV OuOutptpuutt DDDD Cost Effective Applications Mobile Applications VVVCCCOOO PPPFDFDFD RReessonatonatoror Consumer Electronics Portable Electronics FFFrrraaaccc---NNN CCD Clock for VTR Cameras Low Profile Applications PPLLLL Industrial SStatannddbbyy GNDGND ((ppin1in1)) All Rights Reserved.
